Downy Mildew Clobbers Impatiens
One of California's most adored flowering plants, impatiens, is being threatened by a serious pest. You may have noticed the common garden impatiens missing from nurseries, retail store shelves, and landscapes, parks, and gardens this year.
Impatiens are dying from a relatively new plant disease called impatiens downy mildew, caused by the fungus-like, oomycete pathogen Plasmopara obducens. The pathogen primarily affects varieties of Impatiens walleriana, or hybrids with an I. walleriana parent and wild impatiens (I. balsamina). Note that this pathogen does not affect New Guinea impatiens (Impatiens hawkeri) or other bedding plant genera. This disease develops rapidly, with a few leaves on apparently healthy impatiens beginning to show slight yellowing and stunting followed by development of white, powdery spores on the undersides of leaves, and later, by leaf and flower drop. Plants are likely to become completely defoliated within several weeks. The pathogen produces airborne spores, which can travel for many miles, as well as swimming zoospores and oospores, which can survive within soil and plant debris for long periods and infect healthy plants when replanted in the same area.
Early detection is especially critical for this disease since chemical control has been shown to be ineffective once sporulation begins. Scout routinely to identify and remove diseased plants before epidemics can result. Removing infected plants may limit spread to other areas of the landscape.
Consider growing alternative bedding plants that will grow well in shady areas of the landscape but that will not be affected by the disease. Some examples include Bergenia hybrids, Caladiums, Coral bells, Lobelia, New Guinea impatiens, Sweet alyssum, and wax begonias.

/span>Conference Update: Start Planning for Your MarketPlace!
Caution!
Don't miss this opportunity to add money to your UCCE Master Gardener Program's bank account. That's right, the MarketPlace can help volunteers increase the flow of money into their program's operating budget.
The passion UCCE Master Gardeners have for sharing horticulture with the community is fueled by our love for people and love of plants (or maybe you prefer insects). Regardless of the motivation that brings you to the UCCE Master Gardener program, we all have one thing in common - we must periodically purchase items for our gardens!
Historically, conference attendees arrive with empty suitcase space specifically intended for transporting home newly acquired treasures. The MarketPlace is an opportunity to collect unique gardening items while helping individual counties along the way.
Each county has the opportunity to reserve a sales booth space, provide sales materials of their choice and volunteer to assist with store operations. Funds raised by each individual county will be returned to them less minimal operating costs.
Within the next month each UCCE Master Gardener Coordinator will receive an information packet with preliminary participant guidelines. Space may be limited, so keep an eye on the 2014 UC Master Gardener Conference website or the statewide blog for MarketPlace updates. Absolutely, don't allow the information packets to lay dormant or become part of the compost pile.
Start the conversation in your county today, be prepared to respond quickly when the packets arrive in the mail. Talk about how your county can capitalize by participating in the MarketPlace. Brainstorm about what ‘must-have' items will motivate gardeners, naturalists, or bird watchers to part with their hard earned cash. Think about display methods for showcasing your sales items. Offer to coordinate your MarketPlace booth or be a committee participant. Be the one who makes a difference!
Yolo and Sacramento counties are proud to be hosting the 2014 MarketPlace. We look forward to having you join us in Yosemite, one of California's most treasured spots!
A Note of Thanks and Holiday Wishes
Happy Holidays to All!
This Thanksgiving I finished up my bulb planting project and reflected on all of the things I am grateful for. If you’ll indulge me - I’d like to share a few of them with all of you.
- I am thrilled to be a part of the UCCE Master Gardener community and am still reveling in the warm welcome, patience and support as I have been making the transition.
- New staff and positions at the statewide office will help us better address the needs of the UCCE Master Gardeners! Aubrey Bray is enjoying her new position as training coordinator. Aubrey is doing the formative work for online training modules to complement the CA Master Gardener Handbook (new handbook’s ETA is fall 2014). Melissa Womack is settling is as program coordinator and has already shown us how valuable her talents will be to harness the power of our Web based assets throughout the state.
- The University of California Agriculture and Natural Resources (UC ANR) has a beautiful new home. Now all programs and functions within UC ANR are housed in the same building in Davis, Calif. The statewide Master Gardener office moved in early November, and now has direct access to Integrated Pest Management (IPM), Information Technology (IT) and increased visibility to ANR leadership!

News from the Statewide Master Gardener Program
I would like to take a moment to introduce myself, my name is Melissa Womack and I am ecstatic to begin my new role as Program Representative for the University of California Statewide Master Gardeners! I’ve heard a myriad of compliments about the wonderful people involved in the Master Gardener Program across the state of California. Each person I’ve had the opportunity to meet has been helpful, kind and supportive - what a wonderful group of people. I am eager to meet and learn from each of you as my time and experience with the Master Gardeners grows.
Most of my childhood took place in Lake Forest located in Orange County, Calif. After graduating high school I moved to sunny San Diego, Calf. where I received my BA in Communications with an emphasis in Media Management from San Diego State University. After graduating college I moved to the Sacramento area with my husband Jeff. In April of 2010, we welcomed our beautiful daughter into the world.
Professional Experience
The last 10 years of my professional career have been dedicated to marketing and social media. Before accepting a position with the UC Master Gardeners program, I was a key member of an international communications team - responsible for developing policies, best practices and social media branding for a global solar manufacturer.
I believe strongly in the importance of building an engaged online community and am thrilled to see so many Master Gardeners have ‘gone social’! I have a creative eye for design and a passion for photography, which propelled me into corporate video production. My understanding of video helped develop an online video library consisting of product information and training videos. I am excited to advance these skills and confident we will develop a video resource library for Master Gardeners in the future.
I am confident my marketing experience creating and maintaining corporate websites will help develop the functionality of the Master Gardeners Program's resources. In addition, I am looking forward to driving a public awareness campaign for the UCCE Master Gardeners and assisting in digital media management. I am always available to assist with questions surrounding the VMS system and would love to help support your efforts collecting information and resources from UC ANR.
Contact me
I am hopeful my professional experience will bring added value to the Master Gardener Program. If you have any questions or comments feel free to e-mail me directly at mgwomack@ucanr.edu or call me on my direct line 530.750.1388.
I am eager to meet and learn from each of you as my time and experience with the Master Gardeners grows. I am so thankful for the opportunity to join the statewide Master Gardener team, and looking forward to getting to know all of you!
Wishing you a Happy Thanksgiving!
Melissa
/span>Growing Together at the 2014 UC Master Gardener Conference
It feels like just yesterday the University of California Master Gardeners joined together for the 2011 UC Master Gardener Conference at the Hyatt hotel in beautiful Santa Rosa, Calif. It's hard to believe it is already time to start thinking about the 2014 UC Master Gardener Conference on October 7th -10th, 2014 at the gorgeous Tenaya Lodge, near the south entrance of Yosemite National Park.
You Spoke, We Listened!
After each conference the Statewide Master Gardener Conference Committee strives to make the next event bigger and better for attendees. The committee meets following the conference and reviews previous glitches and setbacks to determine solutions and strategies for future conferences. Sounds a lot like gardening, doesn't it?
This year we surveyed UCCE Master Gardeners from across the state and asked, “What topics do you want to see at the 2014 conference?” The committee has been diligently working on securing speakers, site tours and a seminar agenda that came directly as a result from your feedback.
General Track Topics Include:
- Edible Landscaping
- Sustainable Landscaping
- Horticulture
- Integrated Pest Management
- Growing Leaders, Growing Programs
- Art of the Garden
- Master Food Preservers
We are busy lining up speakers for each of topic, check back often for updates!
Conference Highlights Include:
- Keynote speakers
- Networking
- “Search for Excellence Awards”
- Pre and post conference tours
- Silent auction
- Vendor mall
- UC Master Gardener store
- Located at one of California's foremost destinations
The committee is currently in the process of securing sponsorships designed to help reduce registration fees. In hopes of fee reductions, registration costs have not been finalized – and will be announced at a later date.
We hope you will plan on joining us in October at the 2014 UC Master Gardener Conference. Keep up to date with conference information on our website. We will continue to keep you updated with more details as they become available from the committee.
Happy Gardening!
